Can I Refuse an Assignment?

Our most recent PEDS patient, one year old, had back to back seizures and because we are a small facility, he was transferred to a children's hospital once he was stabilized. I'm trying to find out the legal way to handle this situation and whether we have the right to refuse to care for these PEDS patients, at least until we are sufficiently trained. I am not only concerned from a liability standpoint for myself, but extremely concerned for these patients who have nurses with little experience caring for them and even new grad nurses with NO experience with children beyond their college training.
